IMPROVEMENT IN FIRE-SHIELDS.

Specification forming part of Letters Patent No. 169,466, dated November2, 1875; application filed April 24, 1875.

To all whom it may concern:

Be it known that we, THOMAS T. MOORE and DAVID E. BRADLEY, of Chicago,in the county of Cook and State of Illinois, have invented a new anduseful Improvement in Fire- Shields for Buildings; and we do herebydeclare the following to be a full, clear, and exact descriptionthereof, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawing forming a part of this specification.

Our present invention has for its object to improve the invention forwhich Letters Patent were issued to us on the 20th day of April, 1875,No. 162,250; and to that end it consists in the detail construction ofthe plates constitutin g the separate sections of the shield, and in themanner of securing one to the other laterally and to the gable of thebuilding, as

will be more fully understood by the following description and claims.

In the drawing, Figure l is an isometrical view of one of the plates,showing the means employed for securing the same to the gable Fig. 2 isa front elevation of several plates, showing the means employed toconnect them together laterally. Fig. 3 is an isometrical view of adouble plate; and Fig. 4 is a front elevation of one of the plates,showing themanner of connecting the same, so as to adapt it to the angleat the caves of the building.

Similar letters of reference indica te like parts in the several figuresof the drawing.

A represents the plates, constituting the sep- These plates areconstructed so as to admit of being connected together vertically, asand in the manner described in the patent previously mentioned. Bis abar pivoted to one end of a portion of the plates. This bar extendsacross the plate, and is provided on its edge toward the end of theplate with sharp-pointed hooks a a, adapted to take into the roofof thebuilding, and is so arranged on its pivot as to admit of a free and easyoscillating movement, the object of which is to allow the bar to adaptitself to the pitch of different roofs, thus allowing the plates to hangin a vertical position. 0 is a chain or strip of sheet metal, which isprovided with a series of books, d, located at graduated distances onefrom the other, as shown in Fig. 2. These hooks are adapted to take intoan aperture, 0, formed in the center of each plate, the object of whichis to connect the separate sections together laterally, thus preventingthem from being moved by the action of the wind. D is a sheet-metalplate, which is attached to the outersurface of plate A by means offlanges ff, bent at right angles to the plane of the plate, forming anair-chamber, E, between the plates, the object of which is to moreperfectly protect the building from the radiation of the heat.

To arrange the plates so as to allow them to adapt themselves to theangle of the wall, and pitch of the roof atthe eaves, we make a portionof them in two pieces, and hinge them together, as shown at G, Fig. 4.

Having thus described our invention, what we claim is 1. The oscillatingbar B, provided with its hooks to a, in combination with the plate A, asspecified.

2. In combination with the plates forming the separate sections, thechain or bar 0, se-
